mod_php vs context: tight loop
by Brendan Jurd 03 Jan '12

03 Jan '12

Hello list, I have a PHP application which generates documentation on the fly with context. This has been working really well, but I am now testing deployment on a new server with a more recent version of context, and it seems to be somehow getting itself into a tight loop. When I run texexec via the mod_php apache module, the command never returns, and `ps ax` shows the following: 9709 ? S 0:00 sh -c texexec --check 2>&1 9710 ? S 0:00 /bin/sh /usr/bin/texexec --check 9711 ? R 9:59 /usr/bin/texlua /usr/bin/mtxrun --usekpse --execute texexec --check `top` shows the mtxrun process eating 99.9% CPU. Attaching an strace to this process, once it is underway, shows no output. My test script is as follows: <?php $result = null; system("texexec --check 2>&1", $result); print $result . "\n"; ?> When this same test script is run directly from the command line with `php5 -f test.php`, it works as expected and outputs the following: MTXrun | kpse fallback with progname 'context' initialized in 0.01 secondsTeXExec | current distribution: web2c TeXExec | context source date: 2010.07.30 11:35 TeXExec | format path: . /root/.texmf-config/web2c/luatex /root/.texmf-var/web2c/luatex /root/texmf/web2c/luatex /etc/texmf/web2c/luatex /var/lib/texmf/web2c/luatex /usr/local/share/texmf/web2c/luatex /usr/share/texmf/web2c/luatex /usr/share/texmf-texlive/web2c/luatex /root/.texmf-config/web2c /root/.texmf-var/web2c /root/texmf/web2c /etc/texmf/web2c /var/lib/texmf/web2c /usr/local/share/texmf/web2c /usr/share/texmf/web2c /usr/share/texmf-texlive/web2c TeXExec | start of analysis TeXExec | end of analysis TeXExec | TeXExec | TeXExec | version 6.2.1 - 1997-2009 - PRAGMA ADE/POD 0 Using --timeout=30 in the arguments to texexec makes no difference; mtxrun nonetheless runs forever until it is signalled. It seems that this must be down to some kind of difference in Apache's execution environment -- I don't see any other way to explain the same PHP code working in cli and failing in mod_php, even when running as the same user. But what possible environmental factor could lead to mtxrun freaking out like this? I'm hoping someone on this list may be able to point me in the right direction. This server is a VZ instance running under proxmox, with the following relevant ubuntu packages installed (per the 'natty' release): context 2010.07.30-1 libapache2-mod-php5 5.3.5-1ubuntu7.3 apache2 2.2.17-1ubuntu1.4 -- Regards, Brendan Jurd Software Engineer Achieve, Corp brendan.jurd(a)achievecorp.com.au

Center (horizontal + vertical) an image in \setframed
by Jan Heinen 02 Jan '12

02 Jan '12

Hello I want to center (horizontal and vertical) an image in a frame. 1. What Do I have to add? \setlayerframed [Kontaktdaten] [ width=120mm, height=120mm, hoffset=50mm, voffset=50mm ] [strut=no,offset=overlay,frame=on] {\externalfigure[cow][width=100mm,height=100mm]}% 2. This is a complete example. I used a second \setframed to show the area in which the cow should be centered and middled: \definelayer [Kontaktdaten] [x=0mm, y=0mm, width=\paperwidth, height=\paperheight] \setupbackgrounds [paper] [ background=Kontaktdaten, state=start ]% \starttext \setlayerframed [Kontaktdaten] [ width=120mm, height=120mm, hoffset=50mm, voffset=50mm ] [strut=no,offset=overlay,frame=on] {\framed [width=120mm, height=120mm]{~}}% \setlayerframed [Kontaktdaten] [ width=120mm, height=120mm, hoffset=50mm, voffset=50mm ] [strut=no,offset=overlay,frame=on] {\externalfigure[cow][width=100mm,height=100mm]}% test \page \stoptext I wish You a Happy New Year Jannis

indenting \startlines... \stoplines
by Pablo Rodríguez 01 Jan '12

01 Jan '12

Hi there, I want to be a \startlines... \stoplines environment to be 10cm away from the left margin. I know this is a basic question, but I have no idea how to do it. Since this is my last question to the list (this year ;-)), I'd really appreciate, if anyone would be so kind to answer it. Happy New Year, Pablo -- http://www.ousia.tk

new beta
by Hans Hagen 01 Jan '12

01 Jan '12

Hi, I uploaded a new beta. As I'm still in cleaning-up mode, the usual problems could show up as quite some code was adapted (moved around). For those interested there is a file 'status-mkiv' that can be run to get an overview of where we stand. One big change has been the way alignments are initialized. There were two methods (one for \setupalign and one for align keywords) and these have been merged into one. A side effect is that an alignment change is twice as fast as before which might make a difference in excessive usage of \framed and some table mechanisms. Another change is that \color[whatever]{} now always expects an argument (in \MKII {\color[red] ...} is valid too. Some more commands might get that restriction but not the style switchers etc). Again this is twice as fast as the previous method (probably not that noticeable as many switches happen otherwise). For those who won't/didn't get it by snail mail .. this years card can be found at http://www.pragma-ade.com/show-gra.pdf#page=33 In 2012 it will of course again be a gamble if the betas work out well, Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Page Size to Figure Size
by Kip Warner 31 Dec '11

31 Dec '11

Hey list, I have a lot of fairly large diagrams in my book that don't always match the aspect ratio of the page in landscape mode, though they usually are closer to landscape than a portrait layout for the page dimension. How can I insert a figure so that it is of a given size, with the page size perfectly cropped around it? The closest I have right now is this which is rather awful: \definepapersize[main][A4][A4] \definepapersize[diagram][A4,landscape][A4,landscape] % Insert a full page landscape diagram, parameters are node name, caption, and path... \def\FullPageLandscapeDiagram#1#2#3% { \page \setuppapersize[diagram] \setuplayout[fullpage] \startframedtext[width=.95\textwidth,bottom=\vss,top= \vss,align=right,corner=rectangular] \placefigure [force][figure:#1] {#2} {\externalfigure[#3][width=.95 \textwidth,background=color,backgroundcolor=colour_figure_background]} \stopframedtext \page \setuppapersize[main] \setuplayout[reset] } -- Kip Warner -- Software Engineer OpenPGP encrypted/signed mail preferred http://www.thevertigo.com

Header and footer style and arranging
by Aditya Mahajan 31 Dec '11

Header and footer styles do not work with arranging and double sided layout. Minimal example: \setuppapersize[A5][A4,letter] \setuparranging[2SIDE] \setuppagenumbering[alternative=doublesided] \setupheader[style=smallcaps, color=blue] \setupheadertexts[] \setupheadertexts[Hello][][][World] \starttext \input knuth \stoptext Aditya
